Application filed October 22.1906. Serial No. 339.977.

To all whom it may concern:

' Be it known that I, Lnwrs E. WATERMAN, a citizen of the United States, residing'at Rockford, in the county of Winnebago and State of Illinois, have invented certain new is a perspective viewofi the lister, in which the plow is elevated. Fig. 3 is a perspective view of the lister, in which the plow is in work.ng position. Fig. 4isa lan view of the lister, in which certain parts ave been removed in order that the remaining Fig. 5 is a parts may be more clearly seen.

orizontal section through the cam or flat surface 48 of the collar 46 and the lower bar of the yoke. Fig. 6 is a vertical section of the spring connection between the axle and plowbeam. Fig. 7 is an elevation of the rear portion of the frame showing the connection of the caster wheel therewith.

The forward wheels 1 and'2 support an' axle 3 having a bail portion composed of the parallel arms 4 and 5 and an end section 6.

A plow beam 7 is located between the wheels 1 and 2 and has a pivotal connection with the end section 6 by the brackets 8.

"The forward end of the plow beam supports a clevis 9, and the rear turned-down end has a double mold-board plow 10.secured to it. A rolling colter 11 has a connection with the plow beam in any suitable manner.

A foot rest or lever 38 has a fixed connection with the upper section 17 of the casing.

To the section 6 of the hail of the axle is pivoted a link 39, which extends rearward therefrom. To the rear end of this link 39 is pivoted a bar 40 which extends rearward therefrom. -A bracket 41 has a fixed connection with the rear end of the bar 40. This bracket has a tubular vertical opening within which is located a caster-wheel support 42. The caster-wheel is composed of two wheels 43 acting as seed coverers, and a support for the rear portion of the plow beam.

The connection between the bracket 4l and caster-wheel support 42 is formed log a flange 44 on the lower end of the bracket eing received in a recessed collar 45 formed in connection with the collar 46 connected by a set-screw 47 to the caster-wheel support. This connection permits the wheel support to oscillate in the bracket,- at thesame time preventing the disengagement between the parts.

The forward face of the collar 46 has a flat surface 48 with curved ends and located in a vertical plane. A yoke 49 has a pivotal connection with the bracket 41. The lower bar 50 of this yoke rests against the 'flat face 48 of the collar 46, and. one arm of the yoke extends above the pivot of the yoke and has its upper end 51 formed with a horizontal opening.

From the link 39 extends a perforated projection 52., A spring 53 has one end connected to the projection 52,'and its other end. has a connection with the 11 per end. 51 of the yoke 49. The hand-wheel 54 has a screwthread connection with the end of the spring and by which the tension of the spring can be varied. The action of this spring on the yoke 49 is to hold the bar 50 of the yoke yieldingly against the flat surface 48 of the collar 46 and which holds the caster-wheel in proper working position, but permitting it to caster in either direction.

' A link 55 has one end 56 pivoted to the bracket 13 supporting the seed box, and its other end 57 is pivoted to the bracket 41 with which the caster-wheel is connected. A stop 58 is secured to the plow beam and overlies the link 55. A toothed-quadrant 59 is secured to the forward portioirof the bar 40.

A hand-lever 60 has a fixed connection with the rear end of the link39. This hand-lever has the usual dog engagement with the toothed uadrant 59.

From t e rear portion of the link 39 and in rear of the connection of the hand-lever therewith extends a projection 61 which is provided with an opening 62. A foot lever, 63 is located in the opening 62 and has a pivotal connection with the projection 61 on the bolt 64. A link 65 has its lower end pivotally connected to the forward end of the foot lever 63 and its upper end is provided with a lengthwise extending slot 66. A stud 67 extends from the dog 68 of the lifting lever 60 and 66 of the link 65.

From the projection '39 extends an ear 69. To the arm 5 of the bail portion of the axle is passes through the slot overlying the car 69.

through the car 69, and bracket 70. A coiled spring 73 is placed around the bolt 72, one

' in Fig. 1' into the and end resting against the bracket? 1 and its other end-against the nut -74 which has a scre'w threati connection with the bolt 72.

- By means of theban e Q aiidflink 55,-a" pivotal connection 1's it rate between the caster-wheel and .pl'ow beam and between the caster 'wheel and axle.- The hand-lever 60 having a connectionwith the link 39,.and

.the link having a connection with the bail portionof the axle will rock the axle in the supporting-wheels' from f the position shown This movement wi elevate the forward portion of the plow beam. The link 55 forming a connection. between the caster-wheel and rear ortion of the plow-beain serves to raise ower the double mold-board plow attached to the plow-beam.

'VVhen the plow has been lowered to a certain extent, the stop 58 will come in contact with the link 55thereby preventing the independent -movcment of the link in its connection with the plow beam, in order that the point of connection between the link and beam will not drop below a linedrawn be tween the caster-wheel and the connection of the beam with the axle.

By means of the coiled spring 73 a yielding connection is formed between the plow beam and axle. This yielding connection will permit the supporting wheels 1 and 2 to pass ever obstructions or descend into hollows without affecting the running depth of the plow.

From the link-39 extends a projection 75 which extends under the coiled spring 53,

when the plow is lowered to its fullest extent.

the spring 53' will some in contact with this stop and hold the spring from dropping below the center of the axle, that is, pass .the, dead center, which would have the tendency to hold the plow in the ground.

By means of the foot lever '63 the attendant riding in the seat 76 can, with his foot unlock the dog 68 from its engagement with the toothed-quadrant and throw the lifting lever back so that the dog will engage the rear notch of the toothed-quadrant.

By placing the other foot on the rest 38 and pressing down, assistance can be given to raise the plow by foot power.
